Archibald Cox Jr. packs bags again

Archibald Cox Jr., who last summer stunned Wall Street when he resigned as president and chief executive of CS First Boston, has left another job.

Mr. Cox yesterday chose to leave Tiger Management Corp. after he failed to raise $1 billion that the fund management company had targeted for investments in emerging markets, primarily infrastructure projects in China and Southeast Asia.

Mr. Cox, who was not available for comment, was hired expressly to raise the money and manage the fund. When it became clear that his efforts had fallen short, Tiger chose to abort the effort.

"When this fund never materialized, his rationale for being here dematerialized as well," a figure close to the concern said yesterday.

Figures close to Tiger said there was "significant" interest in the fund, and that Mr. Cox had been successful in raising about $250 million.

He is the son of Archibald Cox, the first special prosecutor to investigate the Watergate scandal.
